T o all whom t may concern Be it known that I, OLnN A. COMP, aV

citizen of the United States, residing at Barberton, in the county of Summit and State of Ohio, have invented new and useful Improvements in VVater-Glass Frames,

' of which the following is a specification.

The invention relates to a water glass frame, and more particularly to this type of devices for use on locomotives, boilers, furnaces or the like.

The primary object of the invention is the provision of a water glass frame of this character wherein all danger-is eliminated of the frame or glass working loose with the resultant escape of water or steam.

Another object of the invention is the provision' of a water glass frame wherein the glass is readily and easily'reinoved and is held in the frame without the use of bolts or screws and also eliminates the necessity of detaching the frame when the glass is to be removed therefrom.

A further object of the invention is the provision of a water glass frame wherein the same is rendered perfectly Huid-tight to avoid leakage and also which permits the convenient removal of the glass or the insertion of packing, when the occasion re quires, with despatch.

A still further object of the invention is the provision of a water glass frame of this character which is simple and practical in construction, thoroughly reliable and eliicient in its purpose, strong, durable and inexpensive of manufacture.

lVith these and other objects in view, the invention consists in the features of construction and the combination and arrangement of parts hereinafter described, pointed out in the claims and illustrated in the drawings forming a part of this application.

In the accompanying drawings: Figure 1 is a front elevation of a water glass frame constructed in accordance with the invention; Fig. Q is a top plan view; Fig. 3 is a sectional view` 0n the line 3-3 of Fig. 1; Fig. 4 is a fragmentary vertical longitudinal sectional view through the frame; Fig. 5 is a vertical sectional view showing the body in elevation; Fig. (3 is a perspective view of the facing plato for -the glass, looking toward the inner side thereof; and Fig. 7 is a fragmentary perspective View of the rcinovable gasket,

Similar reference characters indicate correspondin parts throughout the several vlews'of t e drawings.

Referring to the drawings .in detail, the water glass frame ,comprises a body 10jpref erably of elongated rectangular. shape, and is formed in its fronti face with a recess pro-l viding a seat 12vcorrespondingly shaped to f and adapted to receivefthefwaterfglass 13, while integrally formed y,witln/,he said body 10, longitudinally of the Asafinjfat its center, is a pipe-like water vcourse 1/4, while the body at oppositesides of the pipe-like pore tion 14 is transversely beveled and longitu dinally tapered to provide wedging and locking flanges 15 for' the detachable engagement'thereon upon the body of a slide housing 16, hereinafter fully described.

Thelslide housing 16 has formed in its front wall an elongated longitudinally disposed slot 17 forming a sight'opening for the glass 13, which has disposed on opposite sides thereof the gaskets 18, the one at the Y front of the said glass being itted within a facing frame 19 preferably made from metal and having a slot 20 centrallytherein, correspondingly shaped to and adapted to register with the slot 17 in the Afront of the housing so that the height of thev water within the body 10 is clearly visible through the glass on inspecting the gage.

The opposite side walls of the housing 16 are formed with locking fianges 21 beveled and tapered reversely to the ianges 15 and which coperatc with the said flanges 15 for the wedging of the housing 16 upon the body 10 and also to prevent the lateral spreading of the sides of the said housing'when the latter is mounted upon the body to fasten the glass 13 in the latter and also the gaskets which prevent leakage and render the gage fluid-tight.

Upon one side of the body 10 areformed ratchet teeth 22, while mounted in a hearing 23 on one side wall of the housing 16 and working through and opening the slot 24 therein is a spring-hield locking pawl or :latch 25 which engages-with the teeth 22 on the body 10 to lock the housing 1G thereon.

The housing 16,'when removed from the body 10 of the water gage, is inserted upon the upper end of the said body and by a 'blow downwardly thereon the same will be forced into position for the wedging of the said housing on the body and/thereby fastening the glass 13 and the`y gasket 18 to ender the gage fluid-tight. lIt will be clearly therefore, a nioi'e. extended explanation has been oinitted.
